Clear Etchant Crystals 100g (makes 0.5L)

For efficient etching, always use at approximately 45ºC. Normally copper PCB laminate will etch in 5 – 10 minutes. Depending on usage the etching solution will last between 3 and 8 weeks. When the etching time becomes particularly long either replace the liquid or alternatively the solution life can be slightly extended by adding some more crystals.

Makes 0.5L. Add powder to 0.5L of warm water (45ºC) and wait until powder has completely dissolved.
